SIDE FRAME FOR CAR-TRUCKS.

Specification of Letters Patent.

Patented J an. 3d, 1917.

Application filed July 13, 1914. Serial No. 850,635.

To all whom it may concern:

Be it known that I, CLIFTON W. SHER- MAN, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Side Frames for Car-Trucks, of which the following is a specification.

This invention relates to fastening means for securing journal boxes to the side frames of railway trucks and more particularly to cast steel side frames each of which is formed in one piece.

It is the object of this invention to provi de fastening means for this purpose which are simple and inexpensive in construction and capable of being quickly and easily ap plied to and removed from the side frame.

In the accompanying drawings: Figure 1 is a fragmentary side elevation of a truck side frame and journal box showing the left,

side of the latter locked to the frame secured by my improved fastening means. Fig. 2 is a top plan view thereof. Fig. 3 is a vertical transverse section, on an enlarged scale, taken on line 33, Fig. 1. Fig. at is a horizontal section taken on line r4:, Fig. 3. Fig. 5 is a vertical longitudinal section taken on line 5-5, Fig. 4. Figs. 6 and 7 are fragmentary vertical longitudinal sections taken in the correspondingly numbered lines in Fig. ft. Fig. 8 is a fragmentary elevation of the side frame provided with a modified form of the journal box fastening means.

Similar characters of reference indicate corresponding parts throughout the several views.

1 represents one arm of a car truck side frame which is preferably constructed of cast steel and in one piece. Adjacent to the outer end of this arm the same is provided with a guide or socket which receives the axle journal box 2, the guide being formed in the underside of the frame and opening downwardly and having two upright side walls 3, 3 and a horizontal top or abutment a. The journal box engages its upper side 5 with the top of said guide and its vertical side walls 6 with the vertical walls of said guide or socket. The journal box is held against horizontal transverse movement in the guide of the frame by means of front and rear vertical ribs or flanges 7, 8 arranged externally on the vertical walls of the journal box and front and rear horizontal ribs or flanges 9, 10 arranged externally on the top of the same and engaging respectively with the front and rear sides of the frame.

My improvements relate more particularly to the means whereby the journal box is confined against vertical removal from the guide in the frame, and, as shown in Figs. 17, the same are preferably constructed as follows: 11, 11 represents two horizontal locking recesses formed in the opposing parts of the walls of the guide at a distance from the lower end thereof and extending transversely from the front side to the rear side of the frame. 12 represents retaining lugs formed integrally with the side frame and each projecting forwardly from the front side thereof adjacent to the front end of one of the recesses 11 and provided with a vertical opening 13. Each of the vertical stop ribs of the journal box is provided with an outwardly opening notch forming a downwardly facing shoulder 14 on each of these ribs above the adjacent end of one of the recesses 11, and an upwardly facing shoulder 15 on the same below the adjacent end of the respective recess 11. The journal box is introduced into the guide from the lower end of the latter and when the top of this box engages the top of the guide the notches in the vertical ribs are horizontally in line with the recesses of the frame. After the box and frame have been thus assembled they are locked together in this relative position by two keys each of which preferably comprises a body or shank 16 which is inserted in the companion recess and notches in one wall of the guide and the opposing vertical ribs of the box and a lip 17 projecting laterally from the front end of the key body and having a horizontal opening 18 which receives the adjacent locking lug of the frame. The key is prefcrably held against displacement by means of a cotter pin 19 passing through the opening of the locking lug and engaging with the outer or front side of the lip of the respective key. When these parts have been assembled in the manner described the body of each key is held against horizontal displacement in its recess 11 by the pin 19, and against vertical displacement by engaging with the top and bottom of this recess, and the journal box is prevented from moving downwardly in the guide by engagement of the upper shoulders let with the top of the key bodies and the engagement of the lower shoulders 15 with the undersides of the key bodies together with the engagement of the top of the box with the top of the guide limits the upward movement of this box in the guide.

As shown in Fig. 8, the opening in the lip 20 is omit-ted in which case this lipis preferably secured in place between two locking lugs 21, 21 on the front side of the frame by a cotter pin 22 passing 'vertically through these lugsand engaging with the front side of the lip 20. By this means the journal box is securely heldin the guide of the frame and not liable to be displaced or become detached therefrom under the hard est service to which the same may be subj ected. The locking device is very simplein construction and can be produced by forming parts of the same on the side frame and the ournal box without any additional cost.

Owing to the locking devices on both sides of the journal box and frame guide being alike in construction it is possible to place the box in the guide at either end of the frame, thereby avoiding the necessitating of making any of the parts right and left and also facilitating assembling of the parts and reducing the costvofmanufacture as .well as reducing the variety of parts which would otherwise have to be kept on hand to take care of repairs.

I claim as my invention:

1. The combination of a truck side frame having a downwardly opening guide and a recess in a vertical wall of said guideway forming an upwardly facing shoulder, a journal box arranged in said guide way and adapted to be inserted vertically into said guide way and removed vertically therefrom and provided with forwardly and rear- \\1l' Clly facing shoulders engaging with said frame and also provided with a downwardly facing shoulder, and a horizontal key arranged in said recess and between said frame and journal boxand engaging its underside with said upwardly facing shoulder and its upperside with said downwardlv facing shoulder and movable horizontally and transversely into and out of its operative position relatively to said frame and box.

2. The combination of a truck side frame provided with a downwardly opening guide, a recess in a wall of said guide and a lug adjacent to said recess, a journal box ar-- ranged in'saidguide and provided with a downwardly facing shoulder above said recess, and a key having a body arranged in said recess and engaging said shoulder and having a'late'rally projecting lip arranged adjacent to said lug, and a pin arranged in said lug and engag'ing the outer side of said p a .h

The combination of a truck side frame provided with a downwardly opening guide, a recess in a wall of said guide and a lug adjacent to said recess, a journal box arranged in said guide andp'rovided with a downwardly facing shoulder above saidre cess, and a key having a'bo dy arranged in said. recess and engaging said shoulder and having a laterally p'rojectingrlip provided with an opening which receives said lug, and a pin arranged in said lug and engaging with the outer side of said lip. l

l. The combination o'fa truck side frame having a downwardly opening guide the walls of which are vertical, transverse recesses in the opposing parts of said walls, and lugs on the front side of said frame adjacent to the front ends of said recesses, a j ournal box arranged infsaid guide and provided with vertical ribs engaging with the front and rear sides of said frame and hav ing downwardly facing shoulders, keys having transverse bodies arranged in said recesses' and engaging said shoulders and having lips projecting in opposite directions lengthwise of the frame adjacent to said lugs, and pins arranged in said lugs and engaging with the front side of said lips,
